Limited sunshine and spotty showers are possible through the afternoon before rain chances increase later this evening. Storms will likely begin to develop far west around 5 p.m. and gradually spread north and east throughout the evening.

Downpours are likely across our north and western communities Wednesday night through around 3 a.m. Thursday.

A few storms could be strong to severe during this timeframe with damaging wind, frequent lightning and an isolated tornado being the greatest concern.

The highest rainfall totals are likely to occur over the Poconos and Lehigh Valley.

By daybreak Thursday the heaviest rain departs and storm chances isolate in coverage for the afternoon.

Friday and Saturday could feature spotty to widely scattered showers mainly confirmed to the afternoon and evening hours.

The mugginess looks to stick around through at least early next week.
